Assigning materials in MEL

[tb7032]

Hi

this may seem a bit dumb, as i'm new to mel scripting, but i 'm trying to write a script that assigns materials to objects. by watching the mel produced by the gui i have worked out that i need to create a shadergroup (set containing objects to be textured) and connect the outColor attribute of my shader to the surfaceShader attribute of my new surface something like so -

shadingNode -asShader lambert -n shader;
sets -name shaderSG;
connectAttr -f glshader.outColor glshaderSG.surfaceShader;

Unfortunately i get an error saying 'The destination attribute cannot be found' despite the fact that this is the way the gui does it. i realise i'm probably missing something silly here but it is most frustrating. hope somebody can help me here or suggest an alternative way to assign a material to an object in mel.

thanks in advance
tom

oops - i realise there is a typo in the above script - read it as if the shadingNode created is called glshader and the set is called glshaderSG.

this isn't the problem i was posting about....
